feat(connect): Phase 6 — menu-app and manager-app frontend SPAs

Two Vite + React 18 + Tailwind apps under connect_frontend/.
Both use React Router v6, Axios, react-hot-toast, and Lucide icons.
Neither uses localStorage — tokens live in sessionStorage (manager-app)
or component state (menu-app cart).

── menu-app (public menu + ordering) ──────────────────────────────

Routing (basename /menu):
  /:siteSlug              → MenuPage
  /:siteSlug/order        → CartPage
  /:siteSlug/confirm/:ref → OrderConfirm

Pages:
  MenuPage      — fetches menu snapshot, category nav tabs, product
                  cards; floating CartButton; opens ProductModal
  ProductModal  — quantity picker, quick-option toggles, price/discount
                  display, "Add to order" with line total
  CartPage      — order type selector (dine_in/delivery), customer
                  details form, cart summary, submits to cloud API
  OrderConfirm  — polls GET /api/orders/status/:ref every 10s;
                  renders status icon + label; stops polling on
                  terminal states (delivered/rejected)

Components:
  CategoryNav   — horizontal scrollable pill tabs
  ProductCard   — image, name, description, price with discount badge;
                  greyed + "Out of stock" badge when unavailable
  CartButton    — fixed bottom bar with item count + total

── manager-app (remote dashboard) ─────────────────────────────────

Routing (basename /manage):
  /login              → LoginPage
  /                   → SiteSelectorPage (auto-navigates if one site)
  /:siteId            → DashboardPage
  /:siteId/orders     → IncomingOrdersPage
  /:siteId/orders/history → OrderHistoryPage
  /:siteId/orders/:id → OrderDetailPage
  RequireAuth wrapper redirects to /login if no sessionStorage token

Pages:
  LoginPage          — email/password → POST /api/manager/login;
                       stores JWT in sessionStorage
  SiteSelectorPage   — lists accessible venues; auto-selects if one
  DashboardPage      — polls snapshot + pending orders every 15s;
                       2×2 stat grid + pending order list
  IncomingOrdersPage — polls pending orders every 15s; order cards
  OrderDetailPage    — full order detail; Accept/Reject with optional
                       rejection reason; lifecycle progression buttons
                       (Preparing → Ready → Delivered etc.)
  OrderHistoryPage   — all orders with status filter tabs

Components:
  RequireAuth   — route guard using sessionStorage token
  StatCard      — labelled metric tile
  StatusBadge   — colour-coded status pill
  OrderCard     — summary card linking to OrderDetailPage
  (no OrderCard uses useParams to get siteId for nav — wired correctly)
